My Debian graphics issue has been fixed. I’m not exactly sure what the specific problem was, but it works now. I found this while looking for virtualization support in the kernel:

This is a very simple module which allows you to run multiple instances of the same Linux kernel, using the “lguest” command found in the Documentation/lguest directory. Note that “lguest” is pronounced to rhyme with “fell quest”, not “rustyvisor”. See Documentation/lguest/lguest.txt.

If unsure, say N. If curious, say M. If masochistic, say Y.
